RAISING THE LIMIT

Motorists could be allowed to drive through motorway roadworks at 60mph

A Highways England spokesman said smart motorways help stop the "ripple effect" of drivers reaching slow traffic at 70mph and slamming on their brakes.

This causes cars up to a mile back to slow down causing those huge tailbacks for no reason.

He added: "If you start incrementally reducing speed limits and minimise that effect you get more throughput. Very often by the time that person gets there it's been cleared or is on the hard shoulder."
